Abstract

The amount of pesticide migrate was mainly influenced by the rainfall and its interval.Loss of the pesticides such as chlorpyrifos,cypermethrin and chlorothalonil transfer with runoff water ranged from 0.014 kg/hm2 to 0.490 kg/hm2,and the loss rates of the pesticides ranged from 9.79% to 20.51%.If it rain in 3 days after treatment,loss rates of chlorpyrifos and cypermethrin should be 8.32% and 5.58%,respectively,and the rates reduced with 50%.The migration of pesticides with runoff water would reduce and be help to reduce environmental pollution if the application time was adjusted based on rainfall forecast.
